PRINTING-PRESS.

Specification of Letters Patent.

Application filed May 27, 1920. Serial No. 384,536.

T 0 all w from it may concern:

Be it known that I, CLAUDE L. F RIEL, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Printing-Presses, of which the following is a full, clear, and exact description.

My invention relates to job printing presses and particularly to the type known as Gordon presses.

Heretofore when printing the business headings or names of the drawers of checks on pages of check books containing more than one check, it has been customary to immovably adjust the chase in one position for the lower checks, and after printing all of the lower checks readjust the type in the chase for the checks next the lowest and to then print them, and then adjust the type for the checks above the last mentioned checks and so on. The feeding of each sheet of checks in this manner requires great activity on the part of the operator, and involves a great loss of time both in printing them and changing the chase and the makeup of the same.

The object of my invention is to avoid the necessity for such expert labor and the loss of time involved in the changing of the chase and to do this by comparatively inexpensive mechanism that intermittently shifts the chase from one predetermined position to another on the face of the bed, and which can be readily applied to either an old or new press. This I accomplish by the means hereinafter fully described and as illustrated in the drawings, in which:

F igj 8 is a transverse section of the same taken on dotted line 8, 8, Fig. 7.

Fig. 9 is a perspective View of a broken away portion of the chase and carrier therefor, removed from the press.

The job printing press to which my improvements have been applied comprises a supporting frame, between the stationary side-frames A, A, of which the tiltable platen B is mounted. The platen is actuated by mechanism, which is suggested in Fig. l of the drawings, but which, in View of the fact that it does notconstitute any part of my invention and is well known and in extensive use, it is not necessary to describe in detail, further than to say that the drive-shaft C is journaled in said side-frame A, A, and has a flywheel D on one end and a pulley E on the other.

The oscillating frame that supports the bed of the press consists of two corresponding legs 11, 11, the lower ends of which are mounted on a transverse horizontal rockshaft 12 journaled in suitable hearings in the said side-frames A, near the rear edges thereof just above the floor. The upper portions of these legs are shaped so that they are nearer together than their lower portions and are connected by the vertical transversely disposed bed 13 the front of which is perfectly flat and provides a vertical transverse surface that extends from one side-frame to the other for the chase (hereinafter more fully described) to rest against.

The sides of this bed have vertical guidecleats 14-, 1 1, screwed or otherwise secured to the same, and the vertical edges of the rear sides of these cleats are rabbeted to form runways for the end edges of the chase carrier. This carrier consists of end members 15, that are Z-shaped in horizontal secexcept that, as shown in the drawings, it i less in height and the vertical edges of the outer surfaces of its ends are rabbeted to provide runners 19, that are adapted to slide back of and be retained in place by the overlapping lips 20 of the ends of the carrier.

The object of my invention is to make the first of a cycle of, say, three impressions on sheets each having three checks previously printed thereon, or on sheets having several printed forms ofother matter, which has been fed to the platen B, when the carrier and chase are in the position shown in full lines in Fig. 5 of thedrawings; to make the second impression when they are in the position shown in dotted lines in said figure; to make the third impression when they are in the position shown in Fig. 6 of the drawings, and then to commence the next cycle of impressions by returning the chase to the position shown in. said Fig. 5.

In order to enahlethese impressionstobe made in succession, it is obvious that the 'chase must be given an intermittent movement from one position to the next position in which it must be in, in order to make the successive in'i pressions, In order to accomplish this I secure rods 21 to each end of the carrier which extends downward a distance slightly exceeding the distance which the carrier and chase travel to make their 'shaft are journaled in therear ends of brackets 25 that are secured to and project to 'the rear from legs 11 of theoscillating 29, midway between tliebrackets 25, 25 in which it is journaled, andone end of this shaft extends through its bearings and is provided with a sprocket-wheel'ZiO. This sprocketrwheel3O is driventhrough the medium of a chain 31 by a small sprocketwheel 32 on a horizontal shaft 33,.which is journaled in a standard 34: and in bearings in the adjacent, side-frame in axial alinement withthe rock-shaft, 12,0n which sitions at 120 degrees apart synchronously with the first, second and third positions, so respectively,. occupied. by the carrier and chase in making its three impressions. This ram is so shaped that when the carrier and chase are in their lowest positions to make the first of the cycle of impressions, the friction roller 25 will engage a segment 26 of its periphery approximately one sixth of a circle which is struck from the minor radius of this cam and while the friction wheel engages this segment 26, the carrier and chase will be. stationary. As the friction roller passes out of engagement with the segment 26? it is raised and simultaneously raises levers 23 and the carrier and the chase until it reaches the intermediate segment 26 of the cam, which latter represents the intermediate radius of the cam and holds the chase and carrier stationary in their second position while the second impression is being made. The friction roller then passes out of engagement with segment 26! and is raised so as to raise the levers and the carrier and chase to the third or highest position on the, bed and comesinto engagement with the segment 26 which latter is struck from the major radius of the cam, While the. friction roller is traveling over segment 26 the carrier and chaseare held stationarywhile the press is making thethird impressionof the cycle 11:) of impressions. After the friction roller leaves segment 26" theshape of the perimeter of the cam is such that, saidv roller, levers, carrier and chase drop down to their lowest position at which point the roller engages the minor segment 26 again.

In order toenable the-length of each intermittent movement of the I carrier and chase to beadjusted so as to make each impression register on each check or form in theexact position desired on the sheet that is being printed upon, I have madethe intermediate segment and majorse 'ment adjustable to and from the axis of the camshaft. This I accomplish by'means ofchanneled shoes, 37 and 3 8,that are, respectively, seated in proper positions .overthe seg ments 26 and 26 These ,shoes havescrews 39 and 40, respectively, projectingradia-lly inward into smooth bores 4:4, in the cam which latter has lateral openings 41 that are intersected by said screws. Nuts 42 and 43 are mounted upon the threaded portions of said screws, passing through these openings and by manipulating said nuts, the shoes may be adjusted so as to obtain just the length of the intermittent movement of the chase and carrier to make the impression printed by said chase to register exactly at the point desired on the check or other form printed upon.
